Key Calculus Terms and definitions covered in this textbook

If u = v and w = z , then u + w = v + z

• Angle between vectors

The angle formed by two nonzero vectors sharing a common initial point

• Bounded below

A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

• Constant term

See Polynomial function

• Difference identity

An identity involving a trigonometric function of u - v

• Equilibrium point

A point where the supply curve and demand curve intersect. The corresponding price is the equilibrium price.

• Finite series

Sum of a finite number of terms.

• Hypotenuse

Side opposite the right angle in a right triangle.

• Inverse cosine function

The function y = cos-1 x

• Limit

limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

• Measure of an angle

The number of degrees or radians in an angle

• Parametric curve

The graph of parametric equations.

• Parametrization

A set of parametric equations for a curve.

• Real part of a complex number

See Complex number.

• Reciprocal function

The function ƒ(x) = 1x

• Solve by elimination or substitution

Methods for solving systems of linear equations.

• Standard representation of a vector

A representative arrow with its initial point at the origin

• Standard unit vectors

In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

• Sum of two vectors

<u1, u2> + <v1, v2> = <u1 + v1, u2 + v2> <u1 + v1, u2 + v2, u3 + v3>

• Terminal side of an angle

See Angle.
